您的Pivotal Web Services实例有多少内存?我每个实例有2 GB内存,但随着时间的推移,这些实例只会增长到1或1.2 GB。它们在最初几分钟后运行正常。当没有客户使用时,您的实例是否进入休眠模式?在实例处于休眠状态时,这种情况非常常见。不确定-如何检查?这种情况会在部署后立即发生,客户端在容器运行正常的几秒钟内连接,我在早上重新连接实例时看不到这种情况。您的关键Web服务实例有多少内存?我每个实例有2 GB内存,但随着时间的推移,实例只会增长到1或1.2 GB。它们在最初几分钟后运行正常。当没有客户使用时,您的实例是否进入休眠模式?在实例处于休眠状态时,这种情况非常常见。不确定-如何检查?这种情况会在部署后立即发生,客户端在容器正常运行的几秒钟内连接,例如早上重新连接时,我看不到这种行为
